KPP1LA is a standard SAP Structure so does not store data like a database table does. It can be used to define the fields of other actual tables or to process "CO planning processor: logical screen characteristic table" Information within sap ABAP programs. This is done by declaring abap internal tables, work areas or database tables based on this Structure. These can then be used to store and process the required data appropriately. i.e. DATA: wa_KPP1LA TYPE KPP1LA.
The KPP1LA table consists of various fields, each holding specific information or linking keys about CO planning processor: logical screen characteristic table data available in SAP.
